Microclimate refugia shape microclimatic niches and predict individual variability in post-breeding migration in a partially migratory species. [PDF]

J Anim Ecol
The niche is characterized along a gradient of temperature and microclimate refugia. Individuals in breeding areas with low microclimate refugia availability are more likely to cover larger distances to post‐breeding areas, increasing exposure to risks.

Dispersal Ability Reduces Thermal Specialization and Prevents Climate-Driven Extinctions in a Neotropical Rainforest. [PDF]

Glob Chang Biol
We found that species with higher dispersal ability are less specialized in their temperature tolerances and more likely to persist under climate change. By analyzing more than 6 thousand species of plants, invertebrates, and vertebrates distributed in the Atlantic Rainforest, we show that more mobile species can avoid extinction by shifting locations,

Upper thermal tolerances and vulnerability to global warming in a Brazilian Caatinga fish Astyanax bimaculatus (Linnaeus, 1758) population

Austral Ecology, Volume 47, Issue 6, Page 1157-1161, September 2022., 2022
Abstract Global warming is predicted to increase both average temperatures and the frequency and duration of heat waves. Tropical ectotherms, particularly those living in warm environments are more prone to receive heat impacts. Then, it is crucial to identify those populations already exposed to high temperatures that may be at risk of decimation by ...

Roadkill patterns in Latin American birds and mammals

Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Functional redundancy of Amazonian dung beetles confers community‐level resistance to primary forest disturbance

Biotropica, Volume 53, Issue 6, Page 1510-1521, November 2021., 2021
We collected dung beetles from Amazonian forests and used simulated extinction scenarios to determine how species loss influences community functional structure at regional and local scales. We found that the functional redundancy in the regional pool of species buffers the impact of local species losses and confers community‐level functional ...

Cazadores recolectores tempranos, supervivencia de fauna del pleistoceno (equus sp. y glyptodon sp.) y tecnologia lítica durante el holoceno temprano en la frontera Uruguay-Brasil

Revista de Arqueologia, 2010
On this paper we show records of Pleistocene fauna from the archaeological site of PayPaso 1, located near of the Quarai River. On this site we recovered two extinct species, Equus sp. (ancient horse) e Glyptodon sp.

Discriminação com Três Diferentes Contingências em SΔ: Extinção, Reforçamento e Punição, Extinção e Punição

Interação em Psicologia, 2013
Previous studies reported better efficacy in discrimination training when electric shock (used as punisher or as negative reinforcer stimulus) was combined with extinction in presence of SΔ. The present study explored the generality of such data with Hot

Germinação in vitro e desenvolvimento pós-seminal de plântulas de Pilosocereus aurisetus (Werderm.) Byles & G.D. Rowley (Cactaceae)

Revista Ceres, 2012
Pilosocereus aurisetus é uma espécie de cactos de importância econômica e ambiental que se encontra em risco de extinção. A propagação em áreas naturais ocorre, principalmente, de forma sexuada; entretanto, não há registro da germinação e viabilidade de ...
